E-mail: varacha@fai.utb.cz
Abstract: The lecture describes a feed forward Artificial Neural Network (ANN) synthesis via an Analytic Programming (AP) by means of the ANN creation, learning and optimization. This process encompasses four different fields: Evolutionary Algorithms, Symbolic Regression, ANN and parallel computing to successfully synthetize a suitable ANN within a reasonable time. AP performes well in many separate cases together with different evolutionary algorithms as its “engine”. Direct asynchronous parallelization of SOMA – Self-Organizing Migration Algorithm is applied here to boost AP with unusual efficiency. The ANN synthesis method is applied to the real life problem of Heat Load Prediction function optimization of the heating plant in Komorany (Czech Republic) as well as on cancer classification problem and is compared with other methods. ANN synthesis proved to be a useful and efficient tool for nonlinear modeling and its results were applied to intelligent system controlling an energetic framework of an urban agglomeration.

Plenary Lecture 3
Enhanced Evolutionary Search Algorithms for Multiobjective Optimization in Power Systems
Professor Mihai Gavrilas Departmenet of Power Systems
«Gheorghe Asachi» Technical University of Iasi Romania
E-mail: mgavrilas@yahoo.com
Abstract: The development of electricity networks towards the future smart grids is naturally accompanied by increasing complexity of technical, economical and environmental problems. The new challenges require the development of new techniques and optimization methods, including specific approaches to multiobjective optimization problems.
The presentation will focus on basic and multiobjective optimization methods with application to power system optimization problems. These methods are based on modern Evolutionary Computation (EC) metaheuristics, namely search algorithms based on ordered movement of particles (OMP), such as the Gravitational Search Algorithm (GSA) or the Charged System Search Algorithm (CSSA). As the lecture will emphasize, the performance of these algorithms can be substantially improved using an auxiliary mechanism called “dynamic supervision”, specially designed for escaping from local minima.
At the same time, the increasing number of actors in the electricity industry, along with a more distributed nature of electricity generation and an increasingly active role of consumers in the resource management activities, make the decision making process more and more based on multiobjective approaches. One of the most interesting issues in this context is the optimization problem with conflicting objectives. In this case, beyond the traditional methods such as the weighted sum of objective functions or the bounded objective function, one of the most commonly used technique is based on the principle of Pareto optimality, and can be approached using methods such as Strength Pareto Evolutionary Algorithm (SPEA) or Nondominated Sorting Genetic Algorithm (NSGA). Starting from the principle of Pareto optimality, an original method for handling multiobjective optimization problems using OMP-type search algorithms will be described. The method uses non-dominant sorting and particles clustering based on the rank of the Pareto front where each particle was located.
The implementation of the proposed search algorithms is demonstrated for the case of a classical power systems problem, namely the optimal reactive power compensation or VAR optimization using capacitor banks.
Brief Biography of the Speaker: Mihai Gavrilas was born in Iasi, Romania on February, 6, 1959. He received the M.Sc. degree from the “Gheorghe Asachi” Technical University of Iasi, Romania, in 1984.

Plenary Lecture 4
Applications of the Concept of Virtual Organization in Military Training
Professor Mircea Boşcoianu
“Henri Coandă” Air Force Academy Braşov ROMANIA
E-mail: prorector_cercetare@afahc.ro
Abstract: Multi-Agent System (MAS) is defined as a group of agents with specific roles in the organization which work in a synergic way (the global contribution represents more then the summarization of the contribution of the components). In real world there is an interest to be oriented on networks, based on a dynamic and adaptive process of selection of the abilities and capabilities of different actors and then fused in a single entity (chain value concept).
This application is inspired from the distributive business process (DBP) concept which represents a set of dynamic/temporary processes orientated on developing the final product of Virtual Enterprise (VE). The VE is defined (Camarinha-Mathos, Afsarmanessh,1999) as a “temporary alliance that come together to share skills or core competencies and resources in order to better respond to business opportunities, and who’s cooperation is supported by computer networks”. The key elements are networking and cooperation. A generalized concept of VE is represented by Virtual Organization (VO) which represents collaborative networks of organizations that are not limited by Enterprises.
This application is based on the concept of MAS-VE which is designed and developed by using a proper mechanism to sustain VO based on the cooperation in networks of chain values.
The architecture (the functional structure defined by taking into the elements of the system interface, processes, constrains and behavior) of VO is characterized by a minimal structural definition, but also by the complexity of tasks and restrictions of the processes.
MAS-VO should satisfy a demand with maximal efficiency. The flexibility is expressed by the capability to offer a wide variety of different configurations. More flexibility implies a better management of change by using local decisions and then a parallel dissemination on the whole system.
Military training should consider a multi environment space, in which the virtual component of training should respond to: increased capabilities, embedded and tactical subsystems, joint capabilities. The advantage of a training support infrastructure based on virtual components is expressed by costs, efficiencies, better adaptability, a unique capability of battle staffs to synchronized.

Automatic Face Detection and Recognition Techniques
Dr. Tudor Barbu
Institute of Computer Science of the Romanian Academy Iasi branch
ROMANIA
E-mail: tudbar@iit.tuiasi.ro
Abstract: Face recognition has become a very popular field of research in computer vision, representing both a pattern recognition and biometric domain. It is preferable to many other biometric technologies because of its non- intrusive character and because it is very easy to use. Thus, facial recognition has a critical role in biometric systems and it is also attractive for numerous applications including visual surveillance, access control, robotics and security systems. Face detection and recognition represent two strongly-correlated computer vision processes. Face detection constitutes the first step for any automatic face recognition system. Although there has been a great amount of progress in face detection and recognition so far, numerous issues remain unsolved. In spite of several decades of extensive research the development of a computer-based artificial facial recognition system having capabilities comparable with those of human vision systems represents an unachieved goal. Research of human face detection has to confront many challenging problems, related to viewpoint, outdoor illumination, posing variation with large rotation angles, low image quality, low resolution, occlusion, and background changes in complex real-life scenes. Artificial face recognition is also quite difficult because of some factors, such as viewpoint, lighting conditions, facial expressions, aging effects and occlusions.
There are several known categories of face detection approaches: knowledge-based techniques, feature-based methods, appearance-based approaches and template matching methods. The template matching techniques have been the most investigated during our research. We proposed novel face detection approaches based on human skin identification. A skin detection algorithm based on explicitly defined regions is applied first, then a correlation-based template-matching process is performed on the detected skin regions. The most popular face recognition techniques include Eigenfaces, Fisherfaces, Linear Discriminant Analysis, Elastic Bunch Graph Matching, Hidden Markov Models, Gabor filtering and Dynamic Link Matching neuronal model. During our research we considered original facial recognition techniques based on Eigenfaces and Gabor filters. Our Eigenface-based approach is based on the influential work of Turk and Pentland, proposed in 1991. A continuous differential model for face fature extraction is provided, then the mathematical model is discretized. The second recognition technique uses Gabor filtering in the feature extraction stage. It applies a set of 2D Gabor filters, at various frequencies, orientations and standard deviations, on the facial images. An automatic supervised classifier is used in both face authentication cases.

Grammar-Based System Specification for Fun and Profit
Associate Professor Stefan D. Bruda Dept. of Computer Science
Bishop's University Quebec, Canada E-mail: stefan@bruda.ca
Abstract: The specification of programming languages has long benefited from a powerful system, namely the context-free grammar which allows for a natural language specification and is then "compiled" into an automaton that performs the actual parsing. The same pattern (grammars for specification, automata for implementation) is manifest in the realm of formal methods. Here however tools have been essentially limited to a less powerful formalism;
indeed, most process algebrae used in practice for specifying computing systems are just another name for regular grammars, which are considerably less expressive than their context-free counterparts. Using regular grammars thus limits the constructs that can be specified; recursion in particular can only be used in very limited forms, which makes the specification of complex software impossible for all practical purposes. Still, the reason regular grammars continue to be the norm in formal methods is that certain language-theoretic properties show that context-free languages are paradoxically less expressive than regular language in the context of system specification, they being able to model recursion alright, but unable to model other common scenarios such as concurrency. Recently, new tools based on context-free grammars have emerged; such a success remains however in the realm of automata, that is, they do not have any convenient associated "specification language." On-going research is currently attempting to start on the grammatical side, with the eventual goal of creating process algebrae that are capable of handling both recursion and concurrency. In turn, such algebrae will permit complete specifications for complex application software, which today are simply too complex to handle. In this talk I will present the effort of going beyond regular grammars in formal methods. I will summarize the automata side and I will also outline the grammatical approaches. We will see that such an effort is rich and interesting (hence the "fun" in the title) and also has tremendous practical applications (hence the "profit"). On the other hand, we will also see that numerous challenges (both theoretical and practical) have yet to be tackled.
Brief Biography of the Speaker: Dr. Stefan D. Bruda has a successful career as researcher in Computer Science, with over 50 publications so far. His research has spanned at least four major areas (formal languages and automata, formal methods, parallel computation, and artificial intelligence). His main research interest is now formal methods, but he also continues to be interested in formal languages, more precisely in grammatical approaches to parallelism (which will likely be useful in the area of formal methods). Dr. Bruda's research has been continuously funded by a major federal funding agency (the National Science and Engineering Research Council of Canada) since the start of his professional career. His research has also been funded by provincial agencies and other sources. Dr. Bruda acts as an editor for the Parallel Processing Letters journal. He has been active as a reviewer to several conferences, journals (including Theoretical Computer Science and Parallel Processing Letters), and funding agencies (including NSERC in Canada and the CHIST-ERA Consortium in the European Union). He has been invited two times as plenary speaker to international conferences (but had to decline one). Since December 2011 he is a Senior Member of the Association of Computing Machinery (ACM).

E-mail: mitra@fi.itb.ac.id
Abstract: Distance is a physical quantity that used in many applications. In the field of sensor, distance is a main physical quantity that can be used for many measurements. In this paper, we will show the use of flat coil element for measuring of very small distance (proximity). Based on this ability, we develop sensors for measuring mechanical quantities such as pressure, vibration and moment of force. As a proximity sensor, the flat coil element is used to measure the position of an object (seismic mass) as a function of time. Its working principle is based on position change of a seismic mass that put in front of a flat coil element. The flat coil is a part of a LC oscillator; therefore the change of seismic mass position will change its resonance frequency. Based on the developed flat coil element, we have successfully developed air pressure sensor. The working area of the developed pressure sensor can be set by adjusting the membrane thickness. The flat coil element has also been developed for vibration sensor. Vibration like earthquake is a phenomenon of physics. The characteristics of these vibrations can be used as an early warning system so as to reduce the loss or damage caused by earthquakes. For this purpose the sensor should measure vibration in low frequency area. The developed vibration sensor can be used to measure the vibration until 0.2 Hz.
Finally, we have succeeded in developing the flat coil element for moment of force sensor. The developed sensor showed good reproducibility and good reliability with relative error under 3%. Sensor models based on mathematical approach of each sensor have also been developed.

Network Coding: Preliminaries, Theory and Implementation
Professor Zoran Bojkovic Full Professor of Electrical Engineering
University of Belgrade SERBIA
E-mail: z.bojkovic@yahoo.com
Abstract: This presentation aims to be an invitation to engineers and mathematicians to join the work in network theory and implementation, drawing attention to highlights network coding research from the goals and perspectives point of view. At the same time, it is of importance to pave the way towards future theoretical and practical research and development in this area. Network coding (NC) is a new example in data transmission that combines coding with data propagation over a network. Linear network coding (LNC) adopts linear coding scheme at every node of the network and promises the optimal data transmission rate from the source to all receivers. Linearity enhances engineering simplicity which leads to wide applicability. The idea is that the bits in information flows can be mixed as long as receiving hosts have received sufficient evidence to reconstruct the original packets from the sending hosts.There exists tremendous potential for the theory of NC to affect the design of next generation network protocols.
In the first part of this presentation, some network coding principles will be reviewed. Deep connections between LNC and algebra will be demonstrated, too. Also, it will be pointed out that employing coding at the nodes, network capacity can be increased compared with employing routing alone in the simple network topology known as butterfly network. NC may find practical applications in a wide variety of communication networks and systems, starting from cloud computing systems to mobile applications.On the other hand, a key development of network coding is the fact that the maximum multicast communication capacity can be achieved using only LNC.
The second part of this work, deals with coding across data which has been put to extensive use in today's communication systems at link level. Also, it has been emphasized that applications involving peer-to-peer (P2P) networks, such as video streaming, may become the most promising scenario for NC to be deployed in real-world systems.Conceptually, random NC may be beneficial in both P2P content distribution and live streaming systems (NC in mobile phones, operational on-demand streaming with random network coding). In a wireless setting, transmitting a packet from one node to another causes interference to all nearly nodes. If multiple nodes transmit concurently, their waveforms are linearly superimposed, which makes it harder for a receiver to recover its desired packets. As for reliable physical layer network coding, it involves two complementary questions: (a) how to enable encoders and decoders to exploit interfering signals for efficient function computation, and (b) at the network level, which functions to select in order to enable efficient overall information transfer.

Land Use Changes Modeling Based on Different Approaches: Fuzzy Cognitive Maps, Cellular Automata and Neural Networks
Professor Maria Moise
Faculty of Computer Science for Business Management Romanian American University
Bucharest, ROMANIA E-mail: maria.moise@rau.ro
Abstract: For modeling land use changes there are different approaches based on: Fuzzy Cognitive Maps, Cellular Automata, Neural Network etc. Fuzzy Cognitive Maps (FCMs) approach is a modelling methodology, developed as an expansion of cognitive maps. FCMs belong to the class of neuro–fuzzy systems and they are able to incorporate human knowledge and adapt it through learning procedures. FCMs can be used in different fields for example:
political developments, organizational behaviour and job satisfaction, but also they are capable of modelling scenarios described in terms of significant events or concepts and their cause-effect relationships. One of the most useful aspects of the FCM is its potential for use in decision support as a prediction tool, for example given an initial state of a land use, represented by a set of values of its constituent concepts, a FCM can simulate its evolution over time to predict its future behaviour. Cellular Automata approach based on Cellular Automata models consists on a simulation environment represented by a grid of space (raster cells), in which the state of a cell is changing to another state by using a set of transition rules taking into account the attributes of cells in its vicinities. Although CA models are widely applied to simulate various spatio-temporal phenomena, particularly for modeling land use changes, however the implementing of a CA model and its calibration is complicated because there is a large set of parameters of the transition rules and also the numerical values of these parameters, that must be find. For Cellular Automata calibration there are statistical techniques (logistic and multiple regressions, principal component analysis and multivariate analysis of variance) and computational intelligence techniques (neural network, genetic algorithm and data mining). The Neural Networks have the capacity to recognize and classify patterns through training or learning processes and they can be used in urban studies. They provide a better performance than the statistical techniques, because they better handle uncertainties of spatial data. These approaches were proposed in the “Future Policy Modeling – FUPOL” project, financed by FP7 (www.fupol.eu), for modeling land use, one of the urban policy domains, in order to support the politicians and decision makers of local level for the decision making process.

E-mail: gtont@uoradea.ro
Abstract: Dynamic modeling of multi-agent system interactions and modeling complex dynamic environments request devoted dynamic indicators. In complex dynamic environments under conditions of uncertainty, reliability targets have to be realistic and systematically defined in a meaningful way for marketing, engineering, testing, and production. Potential problems proactively identified and solved during design phase and products launched at or near planned reliability targets eliminate extensive and prolonged improvement efforts after start on. The real-life complex development situations express that the methods applied to new product development process content reliability risks which require assessment and quantification at the earliest stage, extracting relevant information from the process. The lecture proposes the computationally efficient adaptive multi-agent approach of estimation of the shape parameters in a complex data structures approached with exponential gamma distribution as model of life time, reliability and failure rate functions in multi-agent system in complex dynamic environments. The reliability indices of studied systems, approached by the means of Extended Generalized Stochastic Petri Nets (EGSPN) and a method dedicated to nonlinear systems integrate the collaboration of multiple systems components for the purpose of proactive and adaptive management. The numerical simulation performed in the case study validates the correctness of the proposed methodology.
